Fault Code: 227 PID: S232 SPN: 1080 FMI: 3/3 LAMP: Amber SRT: |
Sensor Supply 2 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at sensor supply number 2 circuit. |
Marine application: None, no engine protection for circuit or sensor failure. |
Sensor Supply Voltage Number 2 Circuit
|
Circuit Description
The sensor supply number 2 pin of the electronic control module (ECM)
provides +5 VDC for the intake manifold pressure sensor, and rail fuel pressure sensor. ISB and QSB5.9 use a combined intake manifold pressure/temperature sensor.
Component Location
Sensor supply voltage number 2 is located inside the ECM. Refer to Procedure 100-002 for a detailed component location view.
Shop Talk
High voltage on the +5 VDC supply line can be caused by a signal shorted to battery voltage in the engine harness or connectors, or a failed ECM.
